BUFFlNG-MACHINE.

SPECIFICATION formingpart of Letters Patent No. 748,677, dated January 5, 1904:.

Application filed February 3, 1902. Serial No. 92,267. (No model.)

To all whom it may concern:

- Be it known that we, ERASTUS E. WINK- LEY and BENJAMIN PHILLIPS, citizens of the United States, residing atLynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Buffing-Machines; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to buflingmachines.

In the manufacture of boots and shoes it is customary to clean the bottoms of the soles in order to provide a cleansmooth surface suitable for receiving the dressing and for being polished. This has heretofore been done by means of buffing-machines which comprise a suitable bnffing device, such as a roller or pad, against which the shoe is held by the operator, the shoe being pressed backward and forward beneath the buifing roller or pad and tilted in various directions in order to bring all portions of the sole to be cleaned in cont-act therewith.

The object of the present invention is to provide an automatic buffing-machine by which the soles of shoes may be cleaned without any manipulation of the shoes by the operator except the placing of the shoes upon a shoe-supporting jack and the removal of them therefrom after the buffing operation has been completed.

l/Vith this object in view our invention consists in a buifing-machine provided with a suitable buffing device, means for actuating the same, a shoe-supporting jack, and means for relatively actuating the buffing device and jack to transfer the point of contact of the buliing device over the sole of a shoe supported upon the jack.

Our invention also consists in a bufling-machine provided with a buffing device and a shoe-supporting jack which are relatively actuated to transfer the point ofcontact of the buiiing device over the. sole of a shoe supported upon the jack and with means for changing the relative inclination of the jack and bufiiug device during the buffing operation in order to causethe bufling device to act ments, and combinations of parts which will be hereinafter described and claimed, the advantages of which will be obvious to those skilled in the art.

While our invention, broadly considered,

contemplates theme of any suitable form of buffingdevice-such,for instance,as a buffingrollerwe prefer to use a rotary buffing-pad, as the working surface of such a pad is substantially flat and bears upon a considerable area of the bottom of the sole at all times during the buffing operation, so that any liability of certain portions of the sole being cut away more than other portions is avoided and a smooth and even surface is produced, which result cannot be accomplished with certainty when abufling-roller is employed, as the roller contacts with the surface of the sole at a single line or point and is liable to cut away the sole more at some places than at others, especially when there are inequalities in the density of the stock. The soles of shoes are usually subjected to the buffing operation after the heels have been attached, and a further advantage gained by the use of a rotary buffing-pad is that-by means of such a pad the shank portion of the sole close to the breast'of the heel can be cleaned as well as the other portions of the sole, which result cannot be accomplished by the use of a buding-roll, as will be evident. Y

In embodying our invention in the best form at present known to us we secure the relative movement of the jack and buffing device to transfer the point of contact of the buffing device over the sole of the shoe by moving the jack back and forth beneath the buiiing device, and we produce the change in the relative inclination of the bufling device and jack to cause the buffi ng device to act properly upon the surface of the solo by tipping the buffing device in directions extending laterally and longitudinally of the shoe supported upon the jack.

As we have stated, the buffing operation is usually performed upon the shoe after the heel has been attached thereto, and we have accordingly provided means whereby the jack may be adjusted to cause the breast of the heel, the position of which varies in difierent sizes and styles of shoes, to be brought into close proximity to the buffing device during the movement of the jack, such means in the preferred embodiment of our invention,hereinafter specifically described, consisting of means for adjusting the mechanism for actuating the jack.

In order to enable the shoes to be readily placed u pon the jack and to be re moved therefrom after the buffing operation, we have mounted the jack so as to be movable from a position in which the shoes can be readily placed thereon and removed therefrom,which position we term a position of presentation, to a position in which the sole of the shoe can be acted upon by the buffing device, and we have provided means for connecting the jack to its actuating mechanism after having been so moved. To allow the jack to return to its position of presentation, we have provided means for automatically disconnecting the jack from its actuating mechanism at the end of the buffing operation,which means are preferably arranged to act when the toe portion of the shoe supported on the jack is in proximity to the buffing device. The means for connecting the jack to its actuating mechanism and for disconnecting it therefrom not only allows the jack to move from its operative position to a position in which the shoe can be readily removed therefrom, but also enables a number of jacks and cooperating buffing devices to be used in the same machine, whereby one jack can be connected to its actuating mechanism while the other jack is in aposition of presentation, as will hereinafter be more fully explained. Since the position of the breast of the heel varies with the style or size of shoe being operated upon, we prefer to move the jack from its position of presentation to a position in which the shank portion of the sole close to the breast of the heel is beneath the buffing device and to connect the jack to its actuating mechanism when in such position, the adjusting means of the jack-actuating mechanism allowing the jack to be adjusted after being so connected to bring the breast of the heel in close proximity to the buffing device. To allow the jack to be so moved, we have provided means for raisingthe buffing device above the level of the sole of the shoe after the jack has been disconnected from its actuating mechanism and for holding it in its raised position until the jack is again connected to its actuating mechanism.

Certain of the features of construction and operation above referred to are equally applicable to other forms of machines for operating upon the soles of shoes-such, for instance, as sole-leveling machines of the vibrating-roll typeand as to these features We do not consider our invention as limited to a sole-buffing machine, sole-leveling machines,

or other machines for operating upon the soles of shoes embodying these features of construction, being equally within the purview thereof. Thus we believe that we are the first to provide any form of machine for operating upon the soles of shoes with ajack which is movable from a position of presentation to a position in which the sole of the shoe supported thereon is beneath the device for acting upon the sole of the shoe and with means for connecting the jack to its actuating mechanism when in such position. We also believe that weare the first to provide any form of machine for acting upon the soles of shoes with means for connecting the jack to its actuating mechanism when the jack is in a position in which the shank portion of the sole of the shoe is beneath the device for acting upon the sole and with means for disconnecting the jack from its actuating mechanism when the toe of the shoe is in proximity to the device for acting upon the sole of the shoe. We also believe that we are the first to provide any form of machine for operating upon the soles of shoes with means for holding the device for acting upon the soles of shoes above the level of the sole while the jack is being moved into a position beneath the device. We desire, therefore, to be understood as claiming these features of construction and operation whether embodied in a buffing-machine orinotherforms of machines for operating upon the soles of shoes.

A buffing-machine embodying our invention in its preferred form is illustrated in the accompanying drawings, in which Figure l is a View in side elevation thereof. Fig. 2 is a sectional plan view of the machine, taken on the line "2 2 of Fig. 1. Fig. 3 is a detail plan view illustrating the mechanism for supporting and actuating the buifing device, and Fig. t is a detail view illustrating a portion of the mechanism forimparting lateral tipping movements to the buffing device. Referring to the drawings, in which like characters ofreference indicate like parts in the several views, 1 indicates the frame of the machine, and 2 a shaft journaled therein, to which are secured the several cams from which the moving parts of the machine are operated, as will be hereinafter described.

3 indicates the shoe-supportiug jack, which may be of any suitable construction for supporting a shoe and presenting the sole of the shoe to the buffing device, the jack shown being constructed to support an ordinary wooden last. To this end it is provided with a toe-su pport 4 and with a heel-support 5, the upper end of which is provided with a lastpin (not shown) to enter the usual hole in the last. The jack is provided with a hub 6, which is loosely mounted upon a shaft 7, extending across the front portion of the machine-frame parallel with the cam-shaft 2. The jack is capable-of an oscillating movement about the shaft 7 as a pivot in a direction which extends longitudinally of the shoe supported upon the jack and is so oscillated to move the shoe back and forth beneath the buffing device by mechanism which may be described as follows: Secured to the shaft 7 or mounted loosely thereon is the sleeve 8 of a down wardly-projecting arm 9, which is provided with an arc-shaped slot 10. A block 11, provided with a portion which projects into and fits the slot 10 and with a flange projecting over theedge of the arm, is secured to the arm by means ofa set-screw 12, which has a screw-threaded engagement with the flange and bears against the edge of the arm. This block is pivotally connected to one end of a link 13, the other end of which is pivotall; connected to a lever 14, pivoted to the frame of the machine and provided at its free end with a roll or stud which engages a cam groove 15 in the face of a cam-disk 16, secured to the shaft 2.

The above-described construction is such that oscillating movements are imparted to the arm 9 during the revolution of the shaft 2, the extent of which oscillating movements can be varied by adjusting the block 11 on the arm 9 for a purpose which will be hereinafter explained.

The arm 9 is provided with a horizontallyextending portion, upon which is pivotally mounted a spring pressed pawl 17. (See more particularly Fig. 2.) This pawl is adapt- .ed to engagea slot or notch formed in an arm 18, projecting rearwardly from the hub 6 of the jack 3 when thejack is moved into a position to bring the slot in the arm 18 opposite the pawl. When the arm 18 is engaged by the pawl 17, the jack is rigidly connected to the arm 9 and the oscillating movements of the arm are imparted to the jack.

The buffing device is indicated at 19 and, as shown, consists of a rotary pad, the advantages of which over other forms of buffing devices have heretofore been explained. The oscillating movements imparted to the jack transfer the point of contact of the buffing pad back and forth over the sole of a shoe supported upon the jack in a direction ex tending longitudinally of-the shoe. In order to cause the bufiing-pad to act properly upon the irregular curved surface of the sole of the shoe during the oscillating movements of the jack, it is supported and actuated as follows: The buffing-pad is secured to the lower end ofa shaft 20, journaled in bearings in a frame 21, pivotally mounted between the arms of a yoke-shaped frame 22. The frame 22 is socured to a shaft 23, journaled in a frame 24, pivotally mounted upon the upper rear portion of the main frame of-the machine. The

buffing-pad is thus supported so as to be capable of a tipping movement in adirection extending longitudinally of the shoe supported upon the jack, of a tipping movement extending laterally of the shoe supported upon the jack, and of a movement toward and from the surface of the sole, the longitudinal tipping movement being allowed by the pivotal connection between the frames 21 and 22, the lateral tipping movement of the pivotal connection between the frames 22 and 24, formed by the shaft 23, and the movement toward and from the surface of the sole by the pivotal connection between the frame 24 and the main frame of the machine. The frame 21 is oscillated during the operation of the machine to produce a longitudinal tipping movement of the buffing-pad by means of a link'25, one end of which is connected to a projection 26 on the frame 21 and the other end of which isconnected to an arm extending upwardly from a block 27, loosely mounted upon the rear end of the shaft 23. The block 27 is provided with a groove which is engaged by pins projecting inwardly from the forked upper end of a lever 28, the lower end of which is connected by a link 29 to the upper end of a lever 30, the lower end of which is provided with a rollor stud which engages a cam-groove 31 in oneof the faces of the cam-disk 16. The link 29 is adjustably connected to the lower end of the lever 28, as shown in Fig. 1,-whereby the extent of the longitudinal tipping movements imparted to the pad can be varied, if desired. The mechanism for oscillating the frame 24 to tip the bufling-pad in a direction extending transversely to the shoe supported upon the jack consists of a segmental gear 32, a pivotallymounted toothed segment 33, meshing therewith, (see more particularly Fig. 4,) a lever 34, provided with a stud or roll bearing upon 1 a cam-disk 35, secured to the shaft 2, a link 36, connecting the free end of the lever 34 with the segment 33, and a coiled spring 37, arrangedto act on the lever 34 and hold the roller or stud carried thereby in contact with the cam 35.

v A grooved pulley 38 is mounted to rotate freely on the shaft 23 and is continuously rotated from any suitable source of power by a belt (not shown) passing over the pulley. A belt 39 passes over the pulley 38, over two guide-pulleys 40, mounted upon an arm projecting from the segmental gear 32, and over the pulley 41, mounted concentrically with the pivot of frame 21. A belt 42 also passes over the pulley 41, over two guiding-pulleys 43, mounted upon the frame 21, and over a pulley 44 upon the upper end of the shaft 20, to which the buifing-pad is secured. The buflingpad is thus rotated continuously from the pulley 38 through connections which allow the frames 21 and 22 to be oscillated, as above described. In the construction shown in the drawings it will be seen that the axes about which the frames 21 and 22 are oscillated are always located in substantially the same plane as the working surface of the pad, so that the tippingmovements of the pad merely change the relative inclination of the ICC During the buffing operation and while the jack is connected to its actuating mechanism the bufiing-pad is held in contact with the surface of the sole by the weight of the .Various parts supported from the frame 24. After the buffing operation has been completed, however, and after the jack has been disconnected from its actuating mechanism the frame 24 is actuated to raise the buffing-pad above the level of the sole of the shoe supported upon the jack and is held in such position until the jack is again connected to its actuating mechanism. For so actuating the frame 24 a projection 45 is provided on the circumference of the cam-disk 16, which is arranged to engage an arm 46, projecting downwardly from the frame 24. The camdisk 16 is also provided with a lateral projection 47, which is arranged to engage an arm 48, secured to or formed integral with the pawl 17, at the proper time during the operation of the machine and move said pawl out of engagement with the arm 18, and thereby disconnect the jack from its actuating mechanism. When the jack is disconnected from its actuating mechanism, it falls backward against a fixed stop 49 into a position to allow the shoe which has been operated upon to be removed and another shoe to be placed thereon.

The camshaft 2 is rotated by means of a worm 50, which meshes with a worm-gear 51, secured to the shaft 2, the worm 50 being secured to a shaft 52, journaled in the lower portion of the machine-frame at right angles to the cam-shaft. A driving-pulley 53 is mounted to rotate loosely upon the shaft 52 and to be capable of a longitudinal movement on the shaft, and a clutch member 54 is secured to the shaft in a position to be engaged by a clutch member 55, secured to the pulley, when the pulley is moved'on the shaft longitudinally in one direction and to be disengaged therefrom when the pulley is moved in the opposite direction. The pulley 53 is rotated by means of a belt 56, passing'over the pulley'and over a pulley 57, secured to a shaft 58, journaled in the upper portion of the machine-frame. The shaft 58 is driven from any suitable source of power by means of a belt, which also passes over the pulley 57.

' gear 51.

.As a means for throwing the machine into and out of operation a rock-shaft 59 is mounted in the lower portion of the machine-frame parallel with the shaft 52, upon which is loosely mounted an arm 60, which engages a groove formed in the clutch member 55, secured to the pulley 53. An arm 61 is secured to the shaft 59 and extends into the path of movement of a projection 62 on the worm- A coiled spring 63 surrounds the shaft 59 and is connected at one end to the frame of the machine and at the other end to the shaft 59 or to the arm 6l, the tendency of which spring is to rotate the shaft 59 in a direction to bring the arm 61 into the path of movement of the projection 62 and to move the shaft 59 longitudinally in a direction to bring the clutch members 55 and 54 into engagement. A treadle 64, secured to the shaft 59, serves as a means for rotating the shaft against the tension of spring 63 to remove the arm 61 from the path of movement of the projection 62.

Briefly described, the operation of the machine is as follows: When the machine is at rest, the projection 62 is pressed against the arm 61 and the shaft 59 is moved to the left, as viewed in Fig. 1, and the clutch members 54 and 55 are disconnected. Also the jack is disconnected from its actuating mechanism and is in its position of presentation resting against the stop 49. A shoe having been placed in position upon the jack, the jack is moved toward the buffing-pad, which is held raised above the level of the sole of the shoe by theengagement of the projection 45 of the cam-disk 1'6 with the lower end of the arm 46 to allow the shoe to pass beneath the pad. The jack is moved until the shank portion of the sole of the shoe in proximity to the breast of the heel is beneath the bufling-pad, in which position of the jack the arm 18 is opposite the pawl 17, which engages the. armand connects the jack to its actuating mechanism. If necessary, the block 11 is now adjusted on the arm 9 until the breast of the vheel is brought close to the edge of the buffing-pad, the shape of the slot 10 in the arm 9 and the position of the arm being such that the arm, and consequently the jack, is moved by the adjustment of the block 11. The adjustment of the block 11 also changes the extent of the oscillating movements imparted to the jack, so that the extent of such movements corresponds to the distance from the' breast of the heel to the toe of the shoe supported upon the jack. When, therefore, the breast of the heel has been brought close to the edge of the bufiing-pad, the machine has been adjusted for operation upon the particular shoe which has been placed on the jack. The jack-actuating mechanism having been properly adjusted, the operator presses upon the treadle 64, and thereby rocks the shaft 59 to remove the arm 61 from the path of movement of the projection 62, and the spring 63 moves the shaft 59 longitudinally to bring the clutch members 54 and 55 into engagement. During the rotation of the cam; shaft 2 the buffing-pad is allowed to descend into contact with the solo by the removal of the projection 45 from beneath the arm 46, and the jack is moved to transfer the point of contact of the buffing-pad from the breast of the heel to the toe portion of the shoe, then from the toe portion of the shoe back to the breast of the heel, and then again from the breast of the heel to the toe portion of the shoe, at which time in the operation of the machine the parts are in the position illustrated in Fig. 1. During the backward and forward movements of the jack beneath the buffing-pad the pad is tipped longitudinally and laterally to cause the pad to act upon all portions of the sole of a shoe, as has been de-- scribed. The continued rotation of the shaft 2 in the direction indicated by the arrow in Fig. 1 brings the projection 47 in contactwiih the arm 48 of the pawl 17 and moves the pawl out of engagement with the arm 18. The jack being now disconnected from its actuating mechanism falls backward from the bufiing-pad and rests against the stop 49. The cam-shaft continues to rotate until the projection 45 is brought into contact with the arm 46 and actuates the arm to raise the bufiing-pad, and the projection 62 of the gear 51 contacts with the arm 61 and moves the shaft 59 in a direction to disengage theolutch members 54 and 55.

It will be evident that if the cam-shaft 2 is rotated while the jack is disconnected from its actuating mechanism the jack will not be actuated, but will remain in its position of presentation in contact with the stop 49 and that, if desired, a second jack, together with a cooperating buffing device, might be provided, which second jack could be connected to the jack-actuating mechanism and moved back and forth beneath its cooperating buffing device while'the other jack was in its position of presentation, whereby the machine could beoperated continuously, or substantially so, in the same manner as certain well-known sole-leveling machines.
